DESCRIPTION

The Texas Instruments MSP430 family of ultra-low-power microcontrollers consists of several devices featuring

different sets of peripherals targeted for various applications. The architecture, combined with five low-power

modes, is optimized to achieve extended battery life in portable measurement applications. The device features a

powerful 16-bit RISC CPU, 16-bit registers, and constant generators that contribute to maximum code efficiency.

The digitally controlled oscillator (DCO) allows wake-up from low-power modes to active mode in less than 1 µs.

The MSP430G2x55 series are ultra-low-power mixed signal microcontrollers with built-in 16-bit timers, up to 32

I/O touch-sense-enabled pins, a versatile analog comparator, and built-in communication capability using the

universal serial communication interface. For configuration details, see Table 1.

Typical applications include low-cost sensor systems that capture analog signals, convert them to digital values,

and then process the data for display or for transmission to a host system.

SHORT-FORM DESCRIPTION

CPU

The MSP430 CPU has a 16-bit RISC architecture

that is highly transparent to the application. All

operations, other than program-flow instructions, are

performed as register operations in conjunction with

seven addressing modes for source operand and four

addressing modes for destination operand.

The CPU is integrated with 16 registers that provide

reduced instruction execution time. The register-to-

CPU clock.

Four of the registers, R0 to R3, are dedicated as

program counter, stack pointer, status register, and

constant generator, respectively. The remaining

registers are general-purpose registers.

Peripherals are connected to the CPU using data,

address, and control buses, and can be handled with

all instructions.

The instruction set consists of the original 51

instructions with three formats and seven address

modes and additional instructions for the expanded

address range. Each instruction can operate on word

and byte data.

Instruction Set

The instruction set consists of 51 instructions with

three formats and seven address modes. Each

instruction can operate on word and byte data.

Table 3 shows examples of the three types of

instruction formats; Table 4 shows the address

modes.

Operating Modes

The MSP430 has one active mode and five software selectable low-power modes of operation. An interrupt

event can wake up the device from any of the low-power modes, service the request, and restore back to the

low-power mode on return from the interrupt program.

The following six operating modes can be configured by software:

• Active mode (AM)

– All clocks are active.

• Low-power mode 0 (LPM0)

– CPU is disabled.

– ACLK and SMCLK remain active.

– MCLK is disabled.

• Low-power mode 1 (LPM1)

– CPU is disabled

– ACLK and SMCLK remain active.

– MCLK is disabled.

– DCO's dc generator is disabled if DCO not used in active mode.

• Low-power mode 2 (LPM2)

– CPU is disabled.

– ACLK remains active.

– MCLK and SMCLK are disabled.

– DCO's dc generator remains enabled.

• Low-power mode 3 (LPM3)

– CPU is disabled.

– ACLK remains active.

– MCLK and SMCLK are disabled.

– DCO's dc generator is disabled.

• Low-power mode 4 (LPM4)

– CPU is disabled.

– ACLK, MCLK, and SMCLK are disabled.

– DCO's dc generator is disabled.

– Crystal oscillator is stopped.

Interrupt Vector Addresses

The interrupt vectors and the power-up starting address are located in the address range 0FFFFh to 0FFC0h.

The vector contains the 16-bit address of the appropriate interrupt handler instruction sequence.

If the reset vector (located at address 0FFFEh) contains 0FFFFh (for example, flash is not programmed), the

CPU goes into LPM4 immediately after power-up.

(7) This location is used as bootstrap loader security key (BSLSKEY). A 0xAA55 at this location disables the BSL completely. A zero (0h)

disables the erasure of the flash if an invalid password is supplied.

(8) The interrupt vectors at addresses 0FFDEh to 0FFC0h are not used in this device and can be used for regular program code if

necessary.

Most interrupt and module enable bits are collected into the lowest address space. Special function register bits

not allocated to a functional purpose are not physically present in the device. Simple software access is provided

with this arrangement.

Legend rw: Bit can be read and written.

rw-0,1: Bit can be read and written. It is reset or set by PUC.
